Description
[technical field]
The present invention relates to the clear mud device of a kind of boccaro, especially relate to the manufacture craft of the clear mud device of a kind of boccaro.
[background technology]
Known, the peculiar a kind of pottery in Jiangsu, raw material is used to be purple mud, green mud, red soil, be referred to as purple clay, goods are called " boccaro ware ", usually also " boccaro " is called for short, it is a kind of containing irony clayey silt rock for making yixing purple sand device potter's clay used, by jellyfish cloud, quartz, scrap mica, the mineralogical compositions such as irony are formed, pottery can be fired into separately, in yixing purple sand device, dark-red enameled pottery is the most famous, earthenware pot of Yixing make tea not only do not take by force tea it smells really good, again without ripe soup gas, the look of tealeaves can be kept the long period, fragrant, taste, and purple sand tea set any surface finish, though not rest and be rich in gloss, feel is better, nearly one thousand years, boccaro is through producing, the process of development, attain latter stage in maturation to the Ming Dynasty, after this long lasting, for a long time, the advantageous raw material of yixing purple sand, rational chemical constitution, mineral composition, possesses the operational characteristic that plasticity-is good, dry shrinkage is little, for diversified vessel provide good processing condition, boccaro ware is after the manufacture craft of uniqueness forms by a firing, and purple-clay product has good color and luster, heat-shock resistance and ventilation property and water-absorbent, because of its uniqueness is have zonal boccaro resource, but faces exhaustion, restriction exploitation, and real boccaro raw material cannot meet the demand in market, market has occurred the common potter's clay of a large amount of employing adds the personation boccaro ware poor quality of industrial chemicals toning, although similar boccaro resource various places Jun You branch, and the report of boccaro ware is made in paid trial-production, but adopt common mud refining technique, the forming requirements of traditional technology cannot be realized, even if make shaping, the finished product fired, surface is dry and astringent, internal heat weight, poor air permeability, yixing purple sand device color and luster cannot be reached dignified, gentle as beautiful quality requirements, cause the current present situation only having Yixing can make boccaro ware, in order to pass on and develop traditional national culture, protect traditional manufacture craft, can develop the boccaro raw material reaching conventional molding process requirement, adopt new manufacture craft, making it have abundanter color and luster, preferably feel and ventilation property becomes the technology demand of those skilled in the art.
[summary of the invention]
In order to overcome the deficiency in background technology, the invention discloses the manufacture craft of the clear mud device of a kind of boccaro, described manufacture craft obtains the clear mud device of boccaro by mud refining processing step, moulding process step and sintering technology step, the present invention obtains pug in mud refining processing step, shaping through moulding process step, and in sintering technology step, add transmutation mixture, make the boccaro ware burnt out have abundant color and luster, preferably feel and quality, and heat-shock resistance and ventilation property better.
In order to realize the object of foregoing invention, the present invention adopts following technical scheme:
A manufacture craft for the clear mud device of boccaro, comprises mud refining, shaping and fire step,
Wherein mud refining processing step is as follows:
First carry out feedstock capture, mineral aggregate fragmentation, frying decomposition, crushing and screening, the clear mud of layering, squeeze the water out, mud processed and old clod, concrete operation step is as follows:
A, feedstock capture
Gather the boccaro mineral aggregate required for mud refining, stand-by;
B, broken mineral aggregate
The boccaro mineral aggregate that a upper link obtains is carried out being crushed to uniform particles and diameter is less than 5cm;
